Preheat oven to 325°F (163°C). Mix graham cracker crumbs and melted butter until combined. Press mixture firmly into the bottom of a 9-inch springform pan.
In a large bowl, beat cream cheese and sugar with an electric mixer until smooth and creamy.
Add eggs one at a time, beating well after each addition. Stir in vanilla extract and sour cream until just combined.
Pour batter over the crust in the pan and smooth the top with a spatula.
Bake for 50 minutes or until the center is almost set but still slightly jiggly. Turn off oven and let cheesecake sit in oven for 1 hour.
Remove from oven and refrigerate for at least 4 hours before serving.
Notes
For best results, allow the cheesecake to come to room temperature for 20 minutes before slicing.
